Google Nest Learning Thermostat (4th Gen, 2024) with Nest Temperature Sensor - Energy Saving Smart Thermostat - Compatible with Alexa, Apple HomeKit and Google Home App - Polished Gold

Easy to set up and easy to live with. The interface is straightforward enough that anyone in the house can adjust it without asking how, and the app does everything you'd want from across town. The build quality stands out. The display is sharp, the dial has a solid, precise feel to it, and the finish looks like a piece of hardware rather than a plastic box on the wall. The Obsidian color blends in well. The included temperature sensor is a real addition, not a throw-in — it lets you prioritize the room you actually care about instead of whatever room the thermostat happens to be in. Worth what it costs. No complaints.

This is the next level thermostat. If you’re like me, that are always looking to automate everything 😂 then you must have this thermostat. Installation is extremely easy. The app is even more simple to use. WiFi ready and stable connections, you will always have control from anywhere with your phone or Apple Watch (in my case I use Apple products). Very accurate readings and personalized options either from the app or on the device. This is a very good looking and futuristic device, different from the old looking thermostats in the market. This is a great value addition to my almost complete automatic home. I cannot speak about battery as I have installed it wired.

I love my new thermostat! It’s definitely an upgrade from my 2nd generation Nest. It was easy to install, set up and use. Easy on the eyes (at night). I love the mirrored look.

Fantastic! Easy to install. Works with multiple wiring configurations and it senses which wires are connected. My original thermostat was on a wall that got warm during the day due to outdoor heat. I couldn’t regulate a constant room temp. The remote sensor here solved the problem. Google home App is great too! Love the easy programming. I work out in this room and i can now drop the temp before I go in there.

When one of our 3rd Gen Nest Thermostats stopped working, I decided to replace it with a 4th Generation Nest unit. Oddly, the mounting hardware for the 4th Generation is completely different from the 3rd Generation, which is annoying. The wiring backplate is incompatible, as the 4th Generation has a different electrical connector to the thermostat. One nice thing about the new backplate is that there is a light built into the bubble level which signals voltage on the Rh or Rc wires from the HVAC unit, implying you won't need a dedicated C wire for power. Unfortunately, this is many times not the case for the 4th Generation, lit bubble level or not. When I properly mounted and connected the 4th Generation thermostat, the setup app on my phone reported that there was "no power" on the R wire, even though the bubble level was lit, and I could measure the voltage on a multimeter. There was no way to get around the error message in the app. A call to Google support was completely useless. The support person clearly didn't know why the setup app falsely reported "no power", or whether or not the 4th Generation thermostat required higher voltage on the R wires than the 3rd Generation thermostat for operation without a C wire. An internet search revealed numerous people posting on Reddit and other web sites of the same issue I was having. How could Google support not be aware of this? Depending on your view, the difference between the R wire voltage requirements for the 4th Generation from the 3rd Generation thermostats is either an undocumented design change, or a design flaw. Personally, I consider it a significant design flaw, especially that it is not documented in the setup instructions, and there is no warning of this anywhere in Google's documentation. After spending about two hours removing the 3rd Generation mount, installing the 4th Generation mount, waiting for the callback from Google, and figuring out the root cause myself, I unmounted the 4th Generation Nest, packaged it back up, and returned it. I ordered a new 3rd Generation Nest from Amazon, and it works flawlessly with the HVAC unit. One attraction of the 4th Generation Nest is that the "maintenance band", the temperature variance range at which the AC compressor cycles on and off, is manually programmable, while on the 3rd Generation Nest it is not. There have been complaints that the 3rd Generation Nest's maintenance band is only two degrees F wide, which in some climates and homes cycles the compressor too often, and is blamed for excess wear and premature failure on the compressor. (AC units and heat pumps both use compressors.) So if you have a C wire in your compressor-based system, I recommend trying to use a 4th Generation Nest. Another trick which works with both generations is to use a remote sensor in a different part of the room or another room where the ambient temperature doesn't vary as quickly, to reduce compressor cycling. I use this trick for our 3rd Generation Units, and it also works for 4th Generation thermostats. Note that using a remote sensor this way may require some experimentation to get the desired result, while the feature to manually adjust the maintenance band makes it quicker and simpler. I really like the Google Nest thermostats when they're working the way they're supposed to, but the lack of backward functional capability from the 3rd Generation model to 4th Generation model is inexcusable, since there's no warning about it. And Google support is ineffective in helping less technical buyers. The least Google could do is document the issue properly on their web site.

After using the 3rd generation Nest Learning Thermostat, upgrading to the 4th generation has been well worth it. The new design is a noticeable improvement, with the larger display giving it a much more modern and polished appearance on the wall. Beyond the new look, the additional features make the upgrade worthwhile. We have several Nest temperature sensors throughout the house, and I especially like having more flexibility in how those sensors can be used. Rather than simply programming around individual rooms, the ability to work with sensor groups helps provide more balanced comfort throughout the home and makes the overall HVAC setup feel more efficient. The Google Home app integration works well for controlling temperatures, schedules, and sensors in one place. The larger display and Farsight features are also useful improvements in everyday use. Installation was straightforward when replacing our existing Nest, and the included 2nd generation temperature sensor adds even more value to the package. Overall, the combination of the updated design, improved sensor management, smarter features, and better whole-home comfort makes the 4th generation Nest a meaningful upgrade rather than simply a cosmetic refresh.

As finally a lucky homeowner, I'm able to choose my own thermostat. After looking at multiple options, from basic smart to advance smart thermostats, I've always thought the nest was the cream of the crop so went with this latest and smartest model. Instructions and installation equipment were easy to follow and install on a 1986 home. Wi-Fi connectivity and app setup, I had one hiccup if I remember, but was able to complete. I'll quick put my complaints here: one, I like it cold, but I also like energy efficiency. I often find it auto lowering the temperature past where I'd like. I'd use the Eco setting more often, but it's a tad too high. If I want it to stay at a certain temperature, I have to use the hold feature but I still want to be able to adjust it, so then I have to take it off hold. So far it hasn't exactly been learning accurately after about 4 or 5 months of use. Two, it may be fancier than really what I or most people would probably need. The ability to have room sensors is nice. Since sleep temperature is important, I keep it in the master bedroom. Smart integration with Amazon devices and the Google home app, no real problems. A decent number of settings to configure the device as well. All these features make it one of the more expensive options. Three, I mistakenly chose this not realizing it's not an energy star rated model. Not sure exactly why, but it makes it not eligible for power company rebates. This lowers the value proposition. Four, well it's easy enough to use, but not the easiest. I'm by no means technologically illiterate. What I mainly mean is changing the common settings like setting a temperature, switching between hot, cold, and hot / cold, setting a hold, setting eco and changing the temperature thresholds, all required just a little extra work versus other thermostats that have like dedicated arrow buttons. It just comes with the territory of a product designed with a minimalist interface. As for the pros, I've mentioned some. Plenty of features, working smart integration, connectivity if you're into that, sleep design, easy enough installation, and solid build quality. Would I recommend this? If you know what you want and these feature sets are truly what you desire, and price isn't too important, then yes. If you want possibly the best or most advanced, then yes. If you want a basic thermostat, or basic smart thermostat, want something that will save you money sooner than later, want something that's easy for people who don't like technology, then I would not recommend this.

Works amazing, I love the fact that I can control it from my phone and through any smart device. Just tell Alexa to turn on the AC and it’ll get straight to it. And it looks really fancy as well.

Doesn't work in the UK. Even though Amazon are selling this on UK store, compatibility checker tool doesn't work either. I have a 3rd gen heatlink attachment on boiler and it just doesn't work with it. Bad craic really. Stuck with an expensive thing I can't use. Will try send back if I can.

The Google Nest Learning Thermostat (4th Gen) paired with the Nest Temperature Sensor (2nd Gen) has been an excellent upgrade for our home. Installation was straightforward, and the setup through the Google Home app was smooth and intuitive. The thermostat looks sleek and modern, and the display is clear and easy to read. The learning feature works well—after a short adjustment period, it began automatically optimizing our heating and cooling schedule without constant manual input. The temperature sensor is a great addition. It allows us to prioritize comfort in the rooms we actually use, rather than relying solely on the thermostat’s location. This has made a noticeable difference in maintaining consistent temperatures, especially during the night. Energy efficiency is another strong point. We’ve already seen more balanced heating cycles and less unnecessary runtime, which should translate into savings over time. Overall, this is a smart, well-designed product that delivers on both comfort and convenience. Highly recommended for anyone looking to modernize their home climate control system.

Don’t buy if you live in the UK they work, only designed for the USA market. My installer said they don’t work in the UK

I bought a Google Nest Thermostat from Amazon, and initially, I wasn’t sure how to install it. I contacted the supplier, Mr. Mumtaz, who was incredibly helpful. He came over and installed it for me and did such a great job that I ended up getting one more thermostat, which he also installed. The devices are now working perfectly, and I’m very satisfied with the performance. Highly recommend both the product and the excellent service!
